FAN INLET AIRFLOW SENSING ELEMENT
FE-1050 SERIES
DESCRIPTION
The Paragon Controls FE-1050 is an airflow measuring
element assembly specifically designed for installation in the
inlet cone of centrifugal fans or inlet bell of vane-axial fans.
The design of these primary elements provides a means
of accurate measurement of fan capacity along with ease
of installation. Each assembly is complete with two airflow
measuring elements and pivot mounting hardware.
FEATURES
6
• Multiple total and static pressure sensing ports along
the length of the element
• Averaging internal manifold
• Insensitive to flow angle variations of as much as ±20°
when faced in the normal direction of flow
• ±2% accuracy throughout the velocity ranges of 100
fpm and over
FE-1050
Use this formula to calculate the differential pressure (∆ V)
for the transmitter.
V= 1096.7 ∗ √ ∆ P

MOUNTING CONFIGURATION
Minimum Inlet Diameter Installation (Standard)
Mid-bell Installation
Notes:
• The FE-1050 assembly is designed to be installed at the minimum inlet diameter of any fan inlet cone not obstructed by inlet vanes
• FE-1050 elements should not be used on fan inlet applications where the minimum inlet diameter is less tahn 12 inches
• Paragon does not recommend installing FE-1050's at teh minimum inlet diameter when the velocity is greater than 8,000 fpm because the
pressure drop may affect the fan performance and if the velocity is greater than 8,000 fpm a mid-bell installation should be considered
• Mid-bell installation configuration will include 30° angle brackets and a split ring rolled to the exact diameter of the sensing plane for use as
a template to scribe the sensing plane location
• For sensing planes with the same diameter, only one split ring will be provided for use as a template on multiple fans
